FALSE. False because 0.5 is a decimal. it does not go into 12, but 6 does 2 times.

You say 0.5 doesn't go into 12? Where did you get that idea?

12 / 0.5 = 24

Think about it. 0.5 is 1/2. How many halves are there in 1? Aren't there 2?
How many halves are there in 2? Aren't there 4?
0.5 can go into ANY whole number.
